To all whom it may concern:

Be itknown' that I, VILLIAM R. CAMERON, a citizen of the United States, and resident of Boston, county of chusetts, have invented an Improvement in Folding Chairs, of which the following description, in connection with the accompanying drawing, is a specification, J like on the drawing representing like parts. I

This invention has duction of a novel folded into a very and arms being capable of being folded into substantially the plane of the seat, the back and arms at one and the legs at the other side of the seat. My folding chair may be constructed of any material, but preferably it will be made of sheet metal struck into the proper shapes and the sheet meta-lus'ed may be surface for its object theprochair that may be readily treated in any way that metals are combent after the manner of monly treated to guard against rust, or to form a finish, as for instance the metal might be glazed after the manner of socalled agate ware. I Y

My chair may be used for a variety of purposes, as for instance a portable chair for automobile work, or when attending outdoor functions, or it may be used as a. nursery chair. I have herein chosen to illus trate my invention as a nursery chain.

Figure shows a'front elevation of a chair embodying my invention in one good form; Fig. 2 a top view of the chair, Fig. i; Fig. 3 is' a left hand side elevation of the chair, Fig. 1; Fig. 4 a sectional detail of the seat of the chair on the line as, Fig. 2 showing a hinge member forming part of the seat; Fig; 5 is a section in the line as, Fig. 4; Fig. 6 is a section in the line as Fig. 2; Fig. 7 is a section in the line m F'g. 2; Fig. 8 is a section inthe line m, Fig.

Referring to' the drawing,

A represents a seat the rear'edge .of which is slitted and manufacturing hinges to leave separate projections. that are bent or shaped that are embraced by notched and correipondingly bent or eyed projections 5, see

ig. 1, of the chair back B, said e es receiving a rod 6 that serves to hinge t e back to the rear edge of the seat.

" Bothside edges of the seat are alike, see Fig. 4, and the metal ateach side is slitted small space, the legs, back as at 2, 3, 4. to form-eyes.

their uppei: ends and bent to r at intervals, see Fig. 2, said'slits being shown.

and bent at their lower edges to to rm eyes 3. i c thatenter the spaces between the upturned portion a of the seat and apivotor rod 0 is pushed through the eyes a and 0,.thus 3 hinging each arm to the seat.

The side legs D of the chair are cut at that are pushed into the spaces between the formeyes; a?

downturned eyes av and said eyes are piv-.

oted or hinged together by a rod d.

That the side legs D may be braced in their operative posit-ionand the front and back of [the seat be safely sustained, I have v hinged pir jointed to the outer edges of each side legby a pintle or rod 6, braces E, see dotted lines; extended through eyes 03 of the side legs and eyes c of the braces.

The braces when intheir operative positions should, for safety, be. locked, and to provide for this, I have provided the upper end of each front and back brace with a flange 10 that engages. a downturned lip 12 of the teat, yielding portions or spring tongues .13 on the seat acting on the inner sides of said bracesto lock the same together after a flange has engaged a lip 12.

To retain the arms in their operative or uprightposition, as in Figs." 1, 2 and '3, I have combined with said arms and the back locking means shown as a spring tongue or portion 0* integral with each arm C and adapted to engage the front face of fitmelt B of the seat, a flange 6 at each side of the back entering an overturned lip 0* formed on the edge of the adjacent arm C, the s ring tongue of acting to retain the lip and ange in enga ement, see Fig. 8. I

The rent edge of the seat .is shown as provided with a projecting (pdrt'ion or flange .a having its front edge an sides curved or rolled to furnish smooth or round see Figs. 8 and 4. When the seat is cut out to provide a central hole, see F1 2, toconstitute a nursery or hospital 'chair, the blow of the die will be such that in cutting the .hole some of the metal about the hole edge will be turned downwardly forming a lip 20, see Fig. 4, and the downturned portion may be engaged by a lip 21 of part of an india rubber or other usual pad or cushion. g havin a hole, a part of which pad or cushion will form a soft or yielding lining for the ed edges,-

c to disengage the flanges b from the lips with oneof the plies that may be blown up hole, part of said cushion being shown in cushions, orwater-bags,

Figs. 2 and 4, a flap g of the pad or cushion overlying the lip a of the seat.

To shut up my novel folding chair that it may occupy its minimum space and be easily portable, I press outward the spring tongues 0*", thereby unlocking the arms from'the back, fold the back forwardly on the seat, and then fold the arms on to the closed back, this being possible as the hinged rod 65 oocupies a position above the hinge rod 6. Then the means for locking the braces are disengaged from the seat, and said braces are folded inwardly against the inner sides ofthe side legs and the side legs are-then, folded in vardlyj under the seat, the braces lying next theunder side of the seat.

The pador cushion may be inflated in any suitable manner, in which instance the pad will be composed of two plies with a space between," andian air valve will'be connected after the manner of any usual inflated seats,,

Havingf'described my invention, what I claim as new and desire to secure by Patent is 1. A folding chair comprising a seat, side legs, and back and front braces pivotally connected With the side legs, combined with means for locking said front and back braces to the seat substantially at righ: angles to. the side legs, said means including cooperating lips and flanges and normally operative spring tongues. I

2. A folding chair comprising a metallic turned, combined with a back having a se-. ries-of eyes, a rod for connecting the edge of Letters seat, a metallic back pivotally connected therewith and .provided with lips adjacent its side edges, metallic side arms pivotally connected with the seat and provided with flanges to cooperate with the lips on the back, and springtongues on the si es to bear against the front face of the back and retain the lips and flanges in looking engagement. 3. In a folding chair, a metallic seat and H metallic side legs hinged thereto, lips on the seat, front an back braces hinged to the front and back upright edges of the legs and provided with flanges to cooperate with the lips, and spring locking tongues on the seat to automaticallyenga e the braces and retain the flanges thereo' in engagement with the lips, to retain the braces in operative position.

' 4. A folding chair comprising a metallic seat provided at its rear edge with a series ofeyes, and at its ends with't'wo sets of said eyes, one upturned, and the other'downthe back and rear of the seat, arms having a series of eyes, rods} for'hinging the eyes of the arms with the upturnedeyesbf the seat, hinged side legs having a series of eyes, and

downturned eyes of said seat.

In testimony whereof, I have signed my name to thisspecific'ation, inthe presence'of two subscribin witnesses.
